Sample slide (PPTX)

1. Open the sample PPTX file
2. Observe that part of the (small) dotted line is not visible in edit mode.
3. Enter presentation mode
4. Observe that a similiar (but smaller) part of the line is not visible

Version: 7.5.0.0.alpha0+ / LibreOffice Community

All the way back to LibreOffice 6.4. At one point around 7.0 presentation
mode turned much worse, losing larger parts of the line, a regression which
was addressed via bug #136957.

Screenshot in Edit Mode

I see something a bit different. See attached image.

Some segments are thinner than others, but they're visible.
